A kind of processing method of adhesive product

Abstract

The invention discloses a processing method of an adhesive product, which comprises the following steps: (1) compounding double-sided adhesive on the surface of a first release film; (2) forming the double-sided adhesive, using the double-sided adhesive to die-cut into shape The tool punches out the shape of the double-sided adhesive and punches out the set hole, removes the double-sided adhesive waste, and obtains the formed double-sided adhesive; (3) The release film is formed, and the release film and the protective film are sequentially compounded on the surface of the formed double-sided adhesive , use the release film die-cutting tool set to punch out the shape of the release film to obtain a formed release film, remove the waste of the release film and the first release film, and obtain a semi-finished adhesive product. This processing technology uses double-sided adhesive and release film to form separately, so that the double-sided adhesive is not half-cut on the release film, thus avoiding the generation of half-cut knife marks on the release film, and then realizing the processing of adhesive products without knife marks Production.

Description

technical field [0001] The invention relates to a processing method, in particular to a processing method of an adhesive product. Background technique [0002] Die-cutting refers to the process of making raw materials into specific spare parts through precision machining and cutting according to a predetermined shape. In recent years, die-cut adhesive products have been widely used in optoelectronics, communications, computers, automobiles and other industries. They are matched with different components and have functions such as shock resistance, insulation, conductivity, and adhesion. For die-cut adhesive products, in order to facilitate full-page attachment and use, a protective film 1a is used to fix each single-piece product. The structure of common adhesive products such as figure 1 as shown, figure 1 Among them, 1a is a protective film, 2a is a release film, 3a is a double-sided adhesive tape, and 4a is a release film C (or paper). [0003] The existing processing...

Problems solved by technology

In this way, the upper half-cut depth of the release film 2a cannot be effectively controlled in the actual operation process, and it is very easy to have poor overcut, resulting in breakage when the release film 2a is removed. Visual detection, resulting in excessive cuts and bad flow into the client, resulting in customer complaints

In addition, the double-sided adhesive is significantly affected by temperature. When the temperature is high, the double-sided adhesive is prone to overflow. If the adhesive overflows into the knife marks of the release film, it will cause malfunctions such as the release film 2a and the double-sided adhesive 3a.
